Spiral pipe is formed from a coil of metal into a rigid steel tube with a 4-ply spiral lockseam. It has smooth interior for low friction loss with the grooved seam entirely on the outside. This pipe has a resistance to crushing approximately 2 1/2 times that of longitudinal lockseam or welded pipe.
The advantages of high pressure Spiral pipe compared to traditional rectangular duct are numerous and compelling:
Attractive appearance :
exposed Spiral duct is attractive and is frequently specified by architects because of its superior aesthetic appeal. Paintable Spiral duct can be finished to blend in with, or stand out from, the indoor environment.
Economical to install :
• Easier to install through and around structural framing
• Longer spans reduces installation operations and the number of connections and hangers required • Connections are made quickly and easily, and are easier to seal.
